Abstract: Disclosed is a device which provides a logic signal that indicates a true "on air" event during broadcast production. Each audio channel input from a microphone to a mixing console is coupled to a circuit arrangement which determines whether a mute switch is selected, a fader is set for full attenuation, or an input switch is deselected. If none of these events have occurred a signal is provided to an external display which is optically isolated from the mixing console. This signal controls a tally which indicates to a user that the corresponding input channel, for example, from a microphone is active.

Abstract: A detachable two-piece temple (10) having a front piece (12) swivelly attached to the back of an eyeglass frame (80) and a back piece (40) that is quickly, easily and securely attached and detached from the front piece (12). The front piece (12) has extending from its rear surface a resilient locking rod (22), that includes a lock notch (24), and a guide rod (30). The back piece (40) includes a locking rod cavity (50) sized to accept and retain the rod (22), a guide rod cavity (52) that is sized to accept and retain the rod (30), and a locking-rod release opening (54) that has a lock notch catch (56).

Abstract: A mechanism forming the hinges between an eyeglass frame and the lateral temple bars which allows for the rapid adjustment of the vertical alignment of the lens frame in relation to the horizontal axes of the temple pieces. The forward end of each temple piece is split into a stationary half and a sliding half. Each half terminates into a pin or ball which cooperates with a bearing at the edge of the lens frame to form a hinge allowing each temple piece to be folded against the frame. The sliding halves can be moved along the axes of the temple pieces independently from the stationary ones to tilt the hinging axis so as to change the position of the lens plane in relation to the temple pieces.

Abstract: Fitted eyeglass frames having ear engaging members curved to conform to the full contour of the back of the ear they are to engage and moveable rearwardly with respect to the sidebars for releasing the frames for easy removal. In two forms of the invention, the ear engaging members are pivotally attached to the rear ends of the frame sidebars and magnetic and spring means are provided to hold the ear engaging members in desired contact with the ear. In another form of the invention, a spring loaded telescoping section is interposed between the ear engaging members and the sidebars of the frames, and a setscrew acting in the telescoping connection permits adjustment of the effective length of the sidebars.

Abstract: A temple for a spectacle frame has a plug connection between the shaft of the temple and temple end piece first made separately from the shaft of the temple. The plug connection is comprised of a borehole in one of the two elements and a plug on the other of the two elements, which plug is inserted into the borehole, as well as a fixing mechanism for ensuring the relative position between the temple end piece and the shaft. The fixing mechanism has a clamping element, which can assume various axial positions with respect to the peripheral wall surrounding the borehole and which, depending on its axial position, more or less sharply compresses the peripheral wall radially and through this means clamps the plug firmly in the borehole. This design of the fixing mechanism facilitates an exact setting of the length of the temple and of the inner inclination of the temple in adapting it to the geometry of the head of the individual spectacle wearer.

Abstract: A frame for multifocal spectacles includes a side piece attached to each of a pair of lens rims through a hinge mechanism which permits downward rotation of the side piece relative to the rim through a prescribed angle. A nosepad is mounted on each of the lens rims through a level adjusting mechanism by which the nosepad is vertically moved causing the level of the lens rims to be altered in correspondence to the change of inclination of the side piece.By means of the hinge mechanism, through a simple operation, each lens segment of the multifocal lens can be used at the optimum angle with respect to the line of vision, and by means of the level adjusting mechanism for moving the nosepad vertically, each lens segment is moved vertically to the level most suitable relative to the line of vision. At the same time neatness of appearance and decrease of eye fatigue result, whichever pair of lens segments is used.

Abstract: A spectacle-frame side arm is provided which is capable of lateral articulation intermediate its ends to conform to the shape of the wearer's head. The side arm comprises front and rear parts articulated together, and a longitudinal reinforcing lamina extending between the arm parts at least in their zone of articulation. In order to resist torsional stresses about the longitudinal axis of the side arm, the articulated ends of the side-arm parts are formed as interplaced tenons and mortices which extend perpendicularly to the said longitudinal axis. Preferably, the opposing surfaces of the interplaced tenons are separated from each other by a metal spacer element which has a profile similar to that of the articulated ends of the side-arm parts considered in a plane parallel to the longitudinal median plane of the side arm.

Abstract: At the ends of the front part (1) for the lenses, two principal articulations (3) with parallel axes engage two arms (7, 9) adapted to be swung back against the front part (1) and lifted from it for use on the ears. Each arm (7, 9) has a transverse articulation (10) along a transverse axis with respect to the head and common to the two arms, with the frame mounted on the face, so as to permit angulation between the parts (7, 9) of the arm and therefore inclination of the front part (1) and of the lenses along said transverse axis; the two component parts (7, 9) of the two transverse articulations (10) are frictionally connected to each other so as to maintain the inclination imposed on them and thus on the front part. The front part (1) can be folded at the center (at 5).
